China to test world’s second largest solar drone this year

China has made the world’s second largest solar-powered drone and will test its performance in near-space flight this year.

The drone has a wingspan of more than 40 meters, which is wider than the wings of a Boeing 737 passenger plane.
Shi said that it was the second largest solar-powered drone in the world, beaten only by a model by NASA, adding that its performance index and technological capacity were among the most advanced in the world.

The drone has a capacity to fly at an extremely high altitude for a long time and its maintenance is easy and simple, state-run Xinhua news agency quoted him as saying.
